Description

Technical Field

[0001] The utility model relates to the technical field of metal strip passivation cleaning, and particularly relates to a multi-strip metal strip passivation cleaning production line. Background Technique

[0002] The passivation cleaning process is widely used in the surface treatment of metal materials such as stainless steel, carbon steel, and aluminum alloy, and is common in fields such as the automotive industry, aerospace, construction engineering, and electronic equipment. By processing steps such as pickling, passivation, cleaning, and drying, the corrosion resistance and surface quality of the metal can be significantly improved, and the service life of the metal can be extended.

[0003] The passivation cleaning of metal strips is generally carried out in multiple columns simultaneously. In traditional metal strip passivation cleaning devices, the winding or unwinding of metal strips is arranged on the same drive shaft. Although this structure can solve the passivation cleaning work of multiple columns of metal strips, it is difficult to ensure that the tension of each column of metal strips meets the qualified requirements during the winding process.

[0004] A multi-column passivation drive winding connection device for metal strips is disclosed in the Chinese utility model patent with the publication number CN213894615U. Although this device solves the problem that the tension of each roll is basically balanced when multiple columns are wound simultaneously on the take-up shaft, and achieves the purpose that each roll of material on the take-up shaft can be tensioned, in actual production, the lengths of the incoming materials of each coil are inconsistent, and there are limited requirements for the number of joints of the take-up reel. Therefore, when winding, some reels are full while some are not, which will cause inconvenience in taking the reels when multiple columns of metal strips are concentrated on one take-up reel, affecting its production efficiency.

[0005] Therefore, there is an urgent need for a multi-strip metal strip passivation cleaning production line to solve the above problems. Content of the Utility Model

[0034] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0038] In the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] As Figure 1-11 shown, the present utility model provides a passivation and cleaning production line for multiple metal strips. The passivation and cleaning production line for multiple metal strips includes an unwinding mechanism 1, a passivation mechanism 2, a cleaning mechanism 3 and a winding mechanism 6 which are sequentially arranged on the same axis. The unwinding mechanism 1 includes an unwinding machine frame 11 and a plurality of unwinding discs 12 arranged on the side of the unwinding machine frame 11. The distances between the plurality of unwinding discs 12 and the unwinding machine frame 11 are arranged in a progressive manner; a first guide shaft 13 is provided above the outer diameter on the same side of each unwinding disc 12; wherein, the structure of the winding mechanism 6 is the same as that of the unwinding mechanism 1, and the unwinding mechanism 1 and the winding mechanism 6 are symmetrically arranged.

[0040] The passivation and cleaning production line for multiple metal strips provided by the present utility model arranges the distances between the unwinding discs 12 and the unwinding machine frame 11 in a progressive manner, so that the plurality of unwinding discs 12 are not on the same plane, and each unwinding disc 12 independently winds and feeds the material; even if some of the unwinding discs 12 run out of the metal strip inside due to different lengths of the metal strip inside, they can be individually removed and replaced; and the structure of the winding mechanism 6 is the same as that of the unwinding mechanism 1. Therefore, when the metal strip in a certain winding disc 62 is full, it can be individually removed and replaced, making the working efficiency of the production line higher.

[0041] In the present embodiment, as Figure 1 and Figure 11As shown, the unwinding mechanism 1 and the rewinding mechanism 6 have the same structure. The unwinding reel 12 is connected to the side of the unwinding frame 11 through a transmission shaft. There are multiple unwinding reels 12, preferably three. The three unwinding reels 12 are connected to the side of the unwinding frame 11 in a progressive manner. That is, the distances between the three unwinding reels 12 and the side of the unwinding frame 11 are set in an increasing or decreasing manner. Thus, the metal strip in each unwinding reel 12 can be fed in a staggered manner. Since the specifications or batches of the metal strips are different, the lengths of the metal strips in the unwinding reels 12 may vary. Therefore, in the above structure, when the metal strip in a certain unwinding reel 12 is used up in advance or the metal strip in a certain rewinding reel 62 is fully wound in advance, it can be removed and replaced separately. Compared with the traditional structure of setting multiple unwinding reels 12 or rewinding reels 62 on the same transmission shaft, the rewinding reel 62 or the unwinding reel 12 can be replaced without complex disassembly, making the work efficiency higher. In addition, to further improve the work efficiency of this multi-metal strip passivation and cleaning production line, as Figure 11 shown, the unwinding reel 12 or the rewinding reel 62 can be set in an upper and lower two-group structure to increase the number of metal strip unwinding and rewinding, or multiple unwinding mechanisms 1 or rewinding mechanisms 6 can be arranged in parallel to increase the number of metal strip unwinding and rewinding.

[0042] Specifically, the rewinding mechanism 6 and the unwinding mechanism 1 have the same structure. The rewinding mechanism 6 includes a rewinding frame 61 and multiple rewinding reels 62 installed on the side of the rewinding frame 61. Above the outer diameter edge on the same side of each unwinding reel 12, there is a first guide shaft 13. Above the outer diameter edge on the same side of each rewinding reel 62, there is a fourth guide shaft 63. A number of guide grooves are equidistantly arranged on the first guide shaft 13 and the fourth guide shaft 63 respectively. The guide grooves can accurately convey the metal strip from the unwinding reel 12 to the rewinding reel 62 in sequence.

[0043] In this embodiment, as Figure 3 and Figure 4As shown in the figure, the passivation mechanism 2 includes a passivation frame 21, a water storage tank 22 and a passivation tank 23 arranged on the passivation frame 21. The passivation tank 23 is located above the water storage tank 22, and the two are connected by multiple pipes, so that the water in the water storage tank 22 can be recycled in the passivation tank 23. And a chemical agent adding component 24 and a detection component 26 are arranged on the passivation frame 21 near one end of the water storage tank 22. A control module 25 is arranged at the top of the passivation frame 21. The chemical agent adding component 24 and the detection component 26 are respectively in communication connection with the control module 25. The detection component 26 monitors the pH value or conductivity of the water source in the water storage tank 22 at all times, and transmits the monitoring result to the control module 25, so that the control module 25 transmits a signal to drive the chemical agent adding component 24 to add chemical agents into the water storage tank 22 to adjust the concentration in the water storage tank 22. Under the above structure, the passivation mechanism 2 can realize the automatic adjustment and addition of chemical agents, without manual detection and addition, further improving the production efficiency.

[0044] Specifically, as Figure 7 shown in the figure, the detection component 26 includes a cylinder 262 and a detection probe 261. The cylinder 262 is vertically fixed on the passivation frame 21. The detection probe 261 is connected to the output end of the cylinder 262 through two connecting plates, and the detection probe 261 is arranged parallel to the cylinder 262. The cylinder 262 can drive the detection probe 261 to move up and down in the water storage tank 22. When the detection component 26 is not working, the detection probe 261 is suspended above the water storage tank 22. When the detection component 26 needs to detect the water source in the water storage tank 22, the cylinder 262 drives the detection probe 261 to move downward and makes the detection probe 261 immersed in the water source for detection. This setting avoids the corrosion of the detection probe 261 caused by long-term immersion in the water source containing chemical agents.

[0045] Specifically, as Figure 8 shown in the figure, the chemical agent adding component 24 includes a self-priming pump 241 installed on the passivation frame 21. A chemical agent tank 242 is connected to the upper part of the self-priming pump 241 through a pipe. The chemical agent tank 242 is used to store chemical agents. An electronic valve 243 and a flowmeter 244 are successively connected between the chemical agent tank 242 and the self-priming pump 241. The opening and closing of the electronic valve 243 are controlled by the control module 25, and the amount of the chemical agent to be added is limited by the flowmeter 244. The input end of the self-priming pump 241 is connected to the flow connection pipe, and its output end is connected to the water storage tank through a pipe.

[0046] Furthermore, as Figure 5 and Figure 6As shown in the figure, a set of water retaining components 231 are provided at both ends of the passivation tank 23. The water retaining components 231 are composed of two first roller shafts 232 that are pressed against each other. The water retaining components 231 can effectively prevent the water source in the passivation tank 23 from overflowing. Between the two sets of water retaining components 231, two second guiding shafts 233 are provided for further guiding the metal strip; between the two second guiding shafts 233, two pressing members 234 are provided. The pressing members 234 are provided with a number of pressing holes. The metal strip passes through the pressing holes and can be immersed in the water source for passivation and cleaning; in the middle position of the passivation tank 23, a spray head 235 connected to the pipeline of the water storage tank 22 is also provided for water outlet.

[0047] In this embodiment, the structures of the passivation mechanism 2 and the cleaning mechanism 3 are the same; the difference lies in the chemical agents and concentrations in the water sources used for passivation and cleaning.

[0048] As Figure 9 and Figure 10 As shown, the multi-metal strip passivation and cleaning production line is also provided with a driving mechanism 5 and an oven 4. The driving mechanism 5 is arranged between the cleaning mechanism 3 and the winding mechanism 6. The oven 4 is arranged between the cleaning mechanism 3 and the driving mechanism 5. The oven 4 is used for drying the water on the cleaned metal strip; the driving mechanism 5 includes a driving platform 51. The driving platform 51 is provided with a driving component 52 and a third guiding shaft 53. The driving component 52 is composed of two brackets 522 and two second roller shafts 521 installed between the two brackets 522. The two second roller shafts 521 are arranged to be pressed against each other. Between the two ends of the second roller shaft 521 located above and the brackets 522, spring components 523 are also provided. By adjusting the spring components 523 and under the action of the springs, the tension between the two second roller shafts 521 can be adjusted, so as to adjust the driving force of the driving mechanism 5 on the metal strip.

[0049] As Figure 1 As shown, the metal strip is first fed through the unwinding disc 12 on the unwinding mechanism 1. The metal strip sequentially passes through the water retaining components 231, the second guiding shafts 233 and the pressing members 234 in the passivation tank 23, enters the cleaning mechanism 3. After cleaning, it is dried by the oven 4 and a certain driving force is provided by the driving mechanism 5. Finally, it is wound up by the winding disc 62 on the winding mechanism 6. When the metal strip in some winding discs 62 is full, it can be removed and replaced separately, increasing its working efficiency.

[0050] It should be noted that in this embodiment, an electro-degreasing, activation and sealing heating mechanism can also be provided between the unwinding mechanism 1 and the driving mechanism 5 to meet the work of passivating and cleaning the metal strip.

[0051] The above description is only a preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Although the present utility model is disclosed above in a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, when making some changes or modifications using the above-disclosed technical content to form equivalent embodiments of equivalent changes, as long as they do not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical concept of the present utility model shall fall within the scope of the technical solution of the present utility model.
